4.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jacopo Mondi <[email protected]> [ Upstream commit 2b787b66bcb03ec3bd97e950464e0452f459e2ca ] The TW9910 PDN gpio (power down) is listed as active high in the chip manual. It turns out it is actually active low as when set to physical level 0 it actually turns the video decoder power off. Without this patch applied: tw9910 0-0045: Product ID error 1f:2 With this patch applied: tw9910 0-0045: tw9910 Product ID b:0 Fixes: commit "186c446f4b840bd77b79d3dc951ca436cb8abe79" Signed-off-by: Jacopo Mondi <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]> Signed-off-by: Sasha Levin <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- arch/sh/boards/mach-migor/setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/arch/sh/boards/mach-migor/setup.c +++ b/arch/sh/boards/mach-migor/setup.c @@ -359,7 +359,7 @@ static struct gpiod_lookup_table ov7725_ static struct gpiod_lookup_table tw9910_gpios = { .dev_id = "0-0045", .table = { - GPIO_LOOKUP("sh7722_pfc", GPIO_PTT2, "pdn", GPIO_ACTIVE_HIGH), + GPIO_LOOKUP("sh7722_pfc", GPIO_PTT2, "pdn", GPIO_ACTIVE_LOW), GPIO_LOOKUP("sh7722_pfc", GPIO_PTT3, "rstb", GPIO_ACTIVE_LOW), }, };
