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", - };
