This patch series enables support for pwm driver on imx6q SoC. The first patch of the series configure the pinctrl for pwm in device-tree. Actually they are several pin who can be set to pwmO for each pwm, so I assume that all of them must be enabled when configuring pin. The second patch activate stop_enable mode and unset the enable bit during configuration of pwm, and set the enable bit in pwm CR register during enable.
Changes since v1: Remove default pwm pinmux configuration in DT as Shawn and Matt suggested. Now, pwm used pwm's clocks properties to configure pwm's clock. Need Shawn's patch '[PATCH v2 0/4] Move imx6q/28/23 clock lookup over to device tree' to work. Use Benoît's '[PATCH] pwm-imx: Fix config / enable / disable' (un)setting the cr enable bit to enable/disable pwm. The second patch used driver_data instead of cpu_is_xxx macros, to check used architecture and enabled stop_enable mode.
Samir Hachimi (2): Add clock look-up for pwm. Enable Stop_enable mode during configuration of pwm.
