Convert the board to use them. This also fixes issue with recent conversion to GPIO descriptors where GPIO lookup tables were specifying incorrect GPIO chip name ("GPIO" vs "GP"). Fixes: 10a366f36e2a ("ASoC: wm1250-ev1: Convert to GPIO descriptors") Fixes: a45cf3cc72dd ("spi: s3c64xx: Convert to use GPIO descriptors") Fixes: 9a5ed0bac86e ("regulator: wm831x: Convert to use GPIO descriptors") Signed-off-by: Dmitry Torokhov Acked-by: Krzysztof Kozlowski --- arch/arm/mach-s3c/devs.c | 35 ---------- arch/arm/mach-s3c/devs.h | 1 - arch/arm/mach-s3c/mach-crag6410.c | 108 ++++++++++++++++++------------ 3 files changed, 67 insertions(+), 77 deletions(-) diff --git a/arch/arm/mach-s3c/devs.c b/arch/arm/mach-s3c/devs.c index 31827cfc5700..e24967cc648b 100644 --- a/arch/arm/mach-s3c/devs.c +++ b/arch/arm/mach-s3c/devs.c @@ -336,38 +336,3 @@ void __init dwc2_hsotg_set_platdata(struct dwc2_hsotg_plat *pd) npd->phy_exit = s3c_usb_phy_exit;
