|  |  | ||||||
|  | Original patch from Andy Gross. | ||||||
|  |  | ||||||
|  | This patch removes the crci information from the dma | ||||||
|  | channel property.  At least one client device requires | ||||||
|  | using more than one CRCI value for a channel.  This does | ||||||
|  | not match the current binding and the crci information | ||||||
|  | needs to be removed. | ||||||
|  |  | ||||||
|  | Instead, the client device will provide this information | ||||||
|  | via other means. | ||||||

|  |  enabled | ||||||
|  |  | ||||||
|  | If multiple PCIe devices are present in the system, the kernel will | ||||||
|  | panic at boot time when trying to scan the PCI buses. This happens on | ||||||
|  | IPQ806x based platforms, which has 3 PCIe ports. | ||||||
|  |  | ||||||
|  | Enabling this option allows the kernel to assign the pci-domains | ||||||
|  | according to the device-tree content. This allows multiple PCIe | ||||||
|  | controllers to coexist in the system. | ||||||

|  | Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom | ||||||
|  |  | ||||||
|  | ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended | ||||||
|  | on most ARM architectures. This automatically calculate ZRELADDR by | ||||||
|  | masking PHYS_OFFSET with 0xf8000000. | ||||||
|  |  | ||||||
|  | However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware | ||||||
|  | network accelerators, and the bootloader removes this section from the | ||||||
|  | layout passed from the ATAGS (when used). | ||||||
|  |  | ||||||
|  | For newer bootloader, when DT is used, this is not a problem, we just | ||||||
|  | reserve this memory in the device tree. But if the bootloader doesn't | ||||||
|  | have DT support, then ATAGS have to be used. In this case, the ARM | ||||||
|  | decompressor will position the kernel in this low mem, which will not be | ||||||
|  | in the RAM section mapped by the bootloader, which means the kernel will | ||||||
|  | freeze in the middle of the boot process trying to map the memory. | ||||||
|  |  | ||||||
|  | As a work around, this patch allows disabling AUTO_ZRELADDR when | ||||||
|  | ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders | ||||||
|  | which don't support device-tree, which is the case on certain early | ||||||
|  | IPQ806x based designs. | ||||||

|  | Subject: [PATCH 1/8] cpufreq: add Krait dedicated scaling driver | ||||||
|  |  | ||||||
|  | This new driver is based on generic cpufreq-dt driver. | ||||||
|  | Krait SoCs have 2-4 cpu and one shared L2 cache that can | ||||||
|  | operate at different frequency based on the maximum cpu clk | ||||||
|  | across all core. | ||||||
|  | L2 frequency and voltage are scaled on every frequency change | ||||||
|  | if needed. On Krait SoCs is present a bug that can cause | ||||||
|  | transition problem between frequency bin, to workaround this | ||||||
|  | on more than one transition, the L2 frequency is first set to the | ||||||
|  | base rate and then to the target rate. | ||||||
|  | The L2 frequency use the OPP framework and use the opp-level | ||||||
|  | bindings to link the l2 freq to different cpu freq. This is needed | ||||||
|  | as the Krait l2 clk are note mapped 1:1 to the core clks and some | ||||||
|  | of the l2 clk is set based on a range of the cpu clks. If the driver | ||||||
|  | find a broken config (for example no opp-level set) the l2 scaling is | ||||||
|  | skipped. | ||||||

|  | +title: CPU Frequency scaling driver for Krait SoCs | ||||||
|  | + | ||||||
|  | +maintainers: | ||||||
|  | +  - Ansuel Smith <ansuelsmth@gmail.com> | ||||||
|  | + | ||||||
|  | +description: | | ||||||
|  | +  The krait cpufreq driver is a dedicated frequency scaling driver | ||||||
|  | +  based on cpufreq-dt generic driver that scale L2 cache and the | ||||||
|  | +  cores. TEST | ||||||
|  | + | ||||||
|  | +  The L2 cache is scaled based on the max clk across all cores and | ||||||
|  | +  the clock is decided based on the opp-level set in the device tree. | ||||||
|  | + | ||||||
|  | +  Different core freq can be linked to a specific l2 freq and the driver | ||||||
|  | +  on frequency change will scale the core and the l2 clk based of the  | ||||||
|  | +  linked freq. | ||||||
|  | + | ||||||
|  | +  On Krait SoC is present a bug and on every L2 clk change the driver | ||||||
|  | +  needs to set the clk to the idle freq before changing it to the new value. | ||||||
|  | + | ||||||
|  | +  This requires the qcom cpufreq nvmem driver to parse the different opp | ||||||
|  | +  core clk and an additional opp table for the l2 scaling. | ||||||
|  | + | ||||||
|  | +  If the driver detect broken config (for example missing opp-level) the | ||||||
|  | +  cpufreq driver skips the l2 scaling | ||||||
|  | + | ||||||
|  | +  Referring to this example opp-level can be used to link a range of cpu freq | ||||||
|  | +  to a specific l2 freq: | ||||||
|  | +    cpu opp freq 384000000 has opp-level 0 | ||||||
|  | +    l2 opp freq 384000000 has opp-level 0 | ||||||
|  | +    The driver will scale l2 to 384000000 | ||||||
|  | + | ||||||
|  | +    cpu opp freq 600000000-1000000000 has opp-level 1 | ||||||
|  | +    l2 opp freq 1000000000 has opp-level 1 | ||||||
|  | +    The driver will scale l2 to 1000000000 | ||||||

|  | Subject: [PATCH 1/2] mtd: nand: raw: qcom_nandc: add boot_layout_mode support | ||||||
|  |  | ||||||
|  | ipq806x nand have a special ecc configuration for the boot pages. The | ||||||
|  | use of the non-boot pages configuration on boot pages cause I/O error | ||||||
|  | and can cause broken data written to the nand. Add support for this | ||||||
|  | special configuration if the page to be read/write is in the size of the | ||||||
|  | boot pages set by the dts. | ||||||

|  | Subject: dmaengine: qcom: Add ADM driver | ||||||
|  |  | ||||||
|  | Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA | ||||||
|  | controller found in the MSM8x60 and IPQ/APQ8064 platforms. | ||||||
|  |  | ||||||
|  | The ADM supports both memory to memory transactions and memory | ||||||
|  | to/from peripheral device transactions.  The controller also provides | ||||||
|  | flow control capabilities for transactions to/from peripheral devices. | ||||||
|  |  | ||||||
|  | The initial release of this driver supports slave transfers to/from | ||||||
|  | peripherals and also incorporates CRCI (client rate control interface) | ||||||
|  | flow control. | ||||||
|  |  | ||||||
|  | The hardware only supports a 32 bit physical address, so specifying | ||||||
|  | !PHYS_ADDR_T_64BIT gives maximum COMPILE_TEST coverage without having to | ||||||
|  | spend effort on kludging things in the code that will never actually be | ||||||
|  | needed on real hardware. | ||||||

|  |  | ||||||
|  | The current value is probably a typo and is actually uncommon to find | ||||||
|  | 1MB IO space even on a x86 arch. Also with recent changes to the pci | ||||||
|  | driver, pci1 and pci2 now fails to function as any connected device | ||||||
|  | fails any reg read/write. Reduce this to 64K as it should be more than | ||||||
|  | enough and 3 * 64K of total IO space doesn't exceed the IO_SPACE_LIMIT | ||||||
|  | hardcoded for the ARM arch. | ||||||

|  | Subject: net: stmmac: explicitly deassert GMAC_AHB_RESET | ||||||
|  |  | ||||||
|  | We are currently assuming that GMAC_AHB_RESET will already be deasserted | ||||||
|  | by the bootloader. However if this has not been done, probing of the GMAC | ||||||
|  | will fail. To remedy this we must ensure GMAC_AHB_RESET has been deasserted | ||||||
|  | prior to probing. | ||||||
|  |  | ||||||
|  | v2 changes: | ||||||
|  |  - remove NULL condition check for stmmac_ahb_rst in stmmac_main.c | ||||||
|  |  - unwrap dev_err() message in stmmac_main.c | ||||||
|  |  - add PTR_ERR() around plat->stmmac_ahb_rst in stmmac_platform.c | ||||||
|  |  | ||||||
|  | v3 changes: | ||||||
|  |  - add error pointer to dev_err() output | ||||||
|  |  - add reset_control_assert(stmmac_ahb_rst) in stmmac_dvr_remove | ||||||
|  |  - revert PTR_ERR() around plat->stmmac_ahb_rst since this is performed | ||||||
|  |    on the returned value of ret by the calling function | ||||||
