This patch introduces the preliminary support for PMICs X-Powers AXP202 and AXP209. The AXP209 and AXP202 are the PMUs (Power Management Unit) used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company of Allwinner. The core enables support for two subsystems: - PEK (Power Enable Key) - Regulators Signed-off-by: Carlo Caione <carlo@caione.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
