2017-08-21ARM: s3c24xx: Fix NAND ECC mode for mini2440 boardSylwester Nawrocki
After commit e9f66ae23c20 ("mtd: s3c2410: make ecc mode configurable via platform data") booting of the mini2440 board is broken, since for this board we have CONFIG_MTD_NAND_S3C2410_HWECC set. The console gets flooded with errors reported by the mtd subsystem. This patch changes ecc_mode to NAND_ECC_HW which restores proper operation of the NAND flash memory.

If we try anyway, we get a Kconfig warning: warning: (TOSA_BT && H1940BT) selects RFKILL which has unmet direct dependencies (NET) This turns the 'select' into 'depends on' as Krzysztof suggested when I first sent a fix.

2016-09-26dmaengine: s3c24xx: Add dma_slave_map for s3c2440 devicesSam Van Den Berge
This patch updates the s3c24xx dma driver to be able to pass a dma_slave_map array via the platform data. This is needed to be able to use the new, simpler dmaengine API [1]. I used the virtual DMA channels as a parameter for the dma_filter function. By doing that, I could reuse the existing filter function in drivers/dma/s3c24xx-dma.c. I have tested this on my mini2440 board with the audio driver. According to my observations, dma_request_slave_channel in the function dmaengine_pcm_new in the file sound/soc/soc-generic-dmaengine-pcm.c now returns a valid DMA channel whereas before no DMA channel was returned at that point. Entries for DMACH_XD0, DMACH_XD1 and DMACH_TIMER are missing because I don't realy know which driver to use for these.

2016-05-17ARM: Explicitly apply PWM config extracted from pwm_argsBoris Brezillon
Call pwm_apply_args() just after requesting the PWM device so that the polarity and period are initialized according to the information provided in pwm_args. This is an intermediate state, and pwm_apply_args() should be dropped as soon as the atomic PWM infrastructure is in place and the driver makes use of it.

The S3C2440_XTAL_16934400 and S3C2440_XTAL_12000000 symbols are used for both s3c2442 and s3c2440, but Kconfig only allows it to be selected if CPU_S3C2440 is enabled, which can lead to a warning otherwise: warning: (MACH_RX1950) selects S3C2440_XTAL_16934400 which has unmet direct dependencies (ARCH_S3C24XX && CPU_S3C2440) This changes the dependencies to make it possible also for CPU_S3C2442-only configurations.

2015-11-27cpufreq: s3c24xx: Do not mark s3c2410_plls_add as __initArnd Bergmann
s3c2410_plls_add is a device notifier that may be called at runtime and is correctly not marked __init. However it calls s3c_plltab_register() which is marked __init, and that triggers a build error when we are checking for section mismatches: WARNING: vmlinux.o(.text+0x195e0): Section mismatch in reference from the function s3c2410_plls_add() to the function .init.text:s3c_plltab_register() The function s3c2410_plls_add() references the function __init s3c_plltab_register(). This is often because s3c2410_plls_add lacks a __init annotation or the annotation of s3c_plltab_register is wrong. This removes the __init annotation from s3c2410_plls_add as well as the __initdata section annotations from s3c2440_plls_12 and s3c2440_plls_169344, which in turn are referenced from s3c2410_plls_add.
