We need\n> to adjust the local offset from the global number space here.\n> The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c\n> and AFAICT the chip is named \"ath79-gpio\" and the PB44\n> PCF857x expander spawns from this on GPIO 1 and 0. The latter\n> board only use the platform data to specify pins so it can be\n> cut altogether after this.\n> \n> - The MFD Silicon Motion SM501 is a special case. It dynamically\n> spawns an I2C bus off the MFD using sm501_create_subdev().\n> We use an approach to dynamically create a machine descriptor\n> table and attach this to the \"SM501-LOW\" or \"SM501-HIGH\"\n> gpiochip. We use chip-local offsets to grab the right lines.\n> We can get rid of two local static inline helpers as part\n> of this refactoring.\n> \n> Cc: Steven Miao \n> Cc: Ralf Baechle \n> Cc: Lee Jones \n> Cc: Guenter Roeck \n> Cc: Ville Syrjälä \n> Cc: Magnus Damm \n> Cc: Ben Dooks \n> Cc: Heiko Schocher \n> Acked-by: Olof Johansson \n> Signed-off-by: Linus Walleij \n> ---\n> ChangeLog v1->v2:\n> - Fix a minor typo in error path (scl was sda from copy-paste)\n> - Collected Olof's ACK\n> \n> Steven (Blackfin): requesting ACK for Wolfram to take this patch.\n> Ralf (MIPS): requesting ACK for Wolfram to take this patch.\n> Lee: requesting ACK for Wolfram to take this patch.\n> SM501 users: requesting Tested-by on this patch.\n> ---\n> arch/arm/mach-ep93xx/core.c | 39 ++++----\n> arch/arm/mach-ep93xx/edb93xx.c | 15 +--\n> arch/arm/mach-ep93xx/include/mach/platform.h | 4 +-\n> arch/arm/mach-ep93xx/simone.c | 12 +--\n> arch/arm/mach-ep93xx/snappercl15.c | 12 +--\n> arch/arm/mach-ep93xx/vision_ep9307.c | 7 +-\n> arch/arm/mach-ixp4xx/avila-setup.c | 17 +++-\n> arch/arm/mach-ixp4xx/dsmg600-setup.c | 16 +++-\n> arch/arm/mach-ixp4xx/fsg-setup.c | 16 +++-\n> arch/arm/mach-ixp4xx/goramo_mlr.c | 24 ++---\n> arch/arm/mach-ixp4xx/ixdp425-setup.c | 16 +++-\n> arch/arm/mach-ixp4xx/nas100d-setup.c | 16 +++-\n> arch/arm/mach-ixp4xx/nslu2-setup.c | 16 +++-\n> arch/arm/mach-ks8695/board-acs5k.c | 13 ++-\n> arch/arm/mach-pxa/palmz72.c | 12 ++-\n> arch/arm/mach-pxa/viper.c | 27 +++++-\n> arch/arm/mach-sa1100/simpad.c | 12 ++-\n> arch/blackfin/mach-bf533/boards/blackstamp.c | 19 +++-\n> arch/blackfin/mach-bf533/boards/ezkit.c | 18 +++-\n> arch/blackfin/mach-bf533/boards/stamp.c | 18 +++-\n> arch/blackfin/mach-bf561/boards/ezkit.c | 18 +++-\n> arch/mips/alchemy/board-gpr.c | 19 +++-\n> arch/mips/ath79/mach-pb44.c | 16 +++-\n\nFor MIPS:\n\nAcked-by: Ralf Baechle \n\n Ralf","headers":{"Return-Path":"","X-Original-To":"incoming-imx@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming-imx@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=lists.infradead.org\n\t(client-ip=65.50.211.133;
