[linux-sunxi] [PATCH v4 4/9] pwm: sunxi: Customizable control and period register position.

From: Siarhei Volkau sun6i has same registers as sun4i compatible chips, but its position in register map are different. This patch make register's position selectable for support sun6i in next patches. Signed-off-by: Siarhei Volkau ---

[linux-sunxi] [PATCH v4 5/9] pwm: sunxi: Customizable regmap fields and enable bit mask.

From: Siarhei Volkau sun6i has similar control registers bit map in comparison to sun4i channel 0, but each channel has its own control register. This patch make: - regmap fields declarations selectable, - enable/disable bitmask selectable. These things needed for support
