This adds the register offsets for pull up/down for the STMPE 1601, 1801 and 24xx expanders. This is used to bias GPIO lines and keypad lines. Signed-off-by: Linus Walleij <redacted> --- Hi Sam, Lee: I think you should just ACK this so Dmitry can take the patch series through the input tree, where the registers need to be used to enable the keypad on the STMPE2401. --- drivers/mfd/stmpe.c | 4 ++++ drivers/mfd/stmpe.h | 3 +++ include/linux/mfd/stmpe.h | 2 ++ 3 files changed, 9 insertions(+)
Does this need to go in with the other patches in the set? I'm _guessing_ that, as you've sent them separately, they can be applied separately? This needs to go in via MFD, but for my own reference: Acked-by: Lee Jones <redacted>
