I forgot to add that it depends on this patch series (particularly the third patch (3/6) "mfd: axp20x: Add support for AXP813 PMIC") from Chen-Yu: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1428284.html Quentin > Thanks, > Quentin > > Quentin Schulz (2): > Input: axp20x-pek: add support for AXP221 PEK > mfd: axp20x: use correct platform device id for many PEK > > drivers/input/misc/axp20x-pek.c | 62 > ++++++++++++++++++++++++++++++++++------- > drivers/mfd/axp20x.c | 12 ++++---- > 2 files changed, 58 insertions(+), 16 deletions(-) > -- Quentin Schulz, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
