Pull ARM SoC platform updates from Olof Johansson: "SoC platform changes. Main theme this merge window: - The Netx platform (Netx 100/500) platform is removed by Linus Walleij-- the SoC doesn't have active maintainers with hardware, and in discussions with the vendor the agreement was that it's OK to remove. - Russell King has a series of patches that cleans up and refactors SA1101 and RiscPC support" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (47 commits) ARM: stm32: use "depends on" instead of "if" after prompt ARM: sa1100: convert to common clock framework ARM: exynos: Cleanup cppcheck shifting warning ARM: pxa/lubbock: remove lubbock_set_misc_wr() from global view ARM: exynos: Only build MCPM support if used arm: add missing include platform-data/atmel.h ARM: davinci: Use GPIO lookup table for DA850 LEDs ARM: OMAP2: drop explicit assembler architecture ARM: use arch_extension directive instead of arch argument ARM: imx: Switch imx7d to imx-cpufreq-dt for speed-grading ARM: bcm: Enable PINCTRL for ARCH_BRCMSTB ARM: bcm: Enable ARCH_HAS_RESET_CONTROLLER for ARCH_BRCMSTB ARM: riscpc: enable chained scatterlist support ARM: riscpc: reduce IRQ handling code ARM: riscpc: move RiscPC assembly files from arch/arm/lib to mach-rpc ARM: riscpc: parse video information from tagged list ARM: riscpc: add ecard quirk for Atomwide 3port serial card MAINTAINERS: mvebu: Add git entry soc: ti: pm33xx: Add a print while entering RTC only mode with DDR in self-refresh ARM: OMAP2+: Make some variables static ...

ARM: riscpc: dma: use __iomem pointers for writing DMA

2019-05-09T16:16:41+00:00

Use __iomem pointers for efficiency to write the DMA registers. This avoids the compiler emitting several instructions for each access to calculate the register address. Signed-off-by: Russell King

ARM: riscpc: dma: eliminate "cur_sg" scatterlist usage

2019-05-09T16:16:41+00:00

All we really need is the DMA address and size, we don't need the baggage of a full scatterlist structure. Signed-off-by: Russell King

ARM: riscpc: fix DMA

2019-05-09T16:16:41+00:00

DMA got broken a while back in two different ways: 1) a change in the behaviour of disable_irq() to wait for the interrupt to finish executing causes us to deadlock at the end of DMA. 2) a change to avoid modifying the scatterlist left the first transfer uninitialised. DMA is only used with expansion cards, so has gone unnoticed. Fixes: fa4e99899932 ("[ARM] dma: RiscPC: don't modify DMA SG entries") Signed-off-by: Russell King
