Only AXP221 is added for now. AXP223 will be +added after it's Reduced Serial Bus (RSB) interface is supported. + +AXP22x defines a new set of registers, power supplies and regulators, +but most of the API is similar to the AXP20x ones. + +A new irq chip definition is used, even though the available interrupts +on AXP22x is a subset of those on AXP20x. This is done so the interrupt +numbers match those on the datasheet. + +This patch only enables the interrupts, system power-off function, and PEK +sub-device. The regulator driver must first support different variants +before we enable it from the mfd driver. + +Signed-off-by: Boris BREZILLON <boris.brezillon@free-electrons.com> +[wens@csie.org: fix interrupts and move regulators to separate patch] +Signed-off-by: Chen-Yu Tsai <wens@csie.org> +Signed-off-by: Lee Jones <lee.jones@linaro.org> +--- + drivers/mfd/axp20x.c | 98 ++++++++++++++++++++++++++++++++++++++++++++++ + include/linux/mfd/axp20x.h | 86 ++++++++++++++++++++++++++++++++++++++++ + 2 files changed, 184 insertions(+) + +--- a/drivers/mfd/axp20x.c ++++ b/drivers/mfd/axp20x.c +@@ -32,6 +32,7 @@ + static const char * const axp20x_model_names[] = { + "AXP202", + "AXP209", ++ "AXP221", + "AXP288", + };
