From d166629cdf73a60f5fe8646bfe96dfd39c5ba660 Mon Sep 17 00:00:00 2001 From: Wei Chen Date: Mon, 30 Nov 2015 06:05:55 +0000 Subject: pinctrl: atlas7: adjust pin groups of atlas7 nanddisk Remove write-protect and chip-selector pins from nand pin group. And then create two separate pin groups for these two pin. So the nand driver can choose correct pin groups as board desgin: For example: 1. nand without wp&cs: nand@17050000 { pinctrl-0 = <&nd_df_basic_pmx>; }; 2. nand with wp nand@17050000 { pinctrl-0 = <&nd_df_basic_pmx &nd_df_wp_pmx>; }; 3. nand with cs: nand@17050000 { pinctrl-0 = <&nd_df_basic_pmx &nd_df_cs_pmx>; }; 4. nand with wp&cs: nand@17050000 { pinctrl-0 = <&nd_df_basic_pmx &nd_df_wp_pmx &nd_df_cs_pmx>; }; Signed-off-by: Wei Chen Signed-off-by: Barry Song Signed-off-by: Linus Walleij --- drivers/pinctrl/sirf/pinctrl-atlas7.c | 88 +++++++++++------------------------ 1 file changed, 27 insertions(+), 61 deletions(-) (limited to 'drivers/pinctrl/sirf/pinctrl-atlas7.c') diff --git a/drivers/pinctrl/sirf/pinctrl-atlas7.c b/drivers/pinctrl/sirf/pinctrl-atlas7.c index 47c63c5ba4e0..f73eff5b16dd 100644 --- a/drivers/pinctrl/sirf/pinctrl-atlas7.c +++ b/drivers/pinctrl/sirf/pinctrl-atlas7.c @@ -889,12 +889,10 @@ static const unsigned int lr_lcdrom_pins[] = { 73, 54, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 56, 53, 55, };
