extcon: max8997: Fix lack of path setting in USB device mode

2018-11-14T00:06:32Z

MAX8997 driver disables automatic path selection from MicroUSB connector and manually sets path to either UART or USB lines. However the code for setting USB path worked only for USB host mode (when ID pin is set to ground). When standard USB cable (USB device mode) is connected, path registers are not touched. This means that once the non-USB accessory is connected to MAX8997-operated micro USB port, the path is no longer set to USB and USB device mode doesn't work. This patch fixes it by setting USB path both for USB and USB host modes. Signed-off-by: Marek Szyprowski Signed-off-by: Chanwoo Choi

extcon: max8997: Avoid forcing UART path on drive probe

2018-11-12T00:17:13Z

Driver unconditionally forces UART path during probe, probably to ensure that one can get kernel serial log as soon as possible. This approach causes some issues, especially when board is booted with non-UART cable connected to micro-USB port. For example, when USB cable is connected, UART TX/RX lines are unconditionally short-circuited to USB D+/D- lines. This is in turn recognized by a series of serial BREAK signals and some random characters when USB host tries to perform enumeration procedure. To solve the above issue and keep UART console operational as early as possible, set UART path only when USB ID reports UART capable cable.

extcon: cht-wc: Return from default case to avoid warnings

2018-08-28T02:21:15Z

When we have first case to fall through it's not enough to put single comment there to satisfy compiler. Instead of doing that, return fall back value directly from default case. This to avoid following warnings: drivers/extcon/extcon-intel-cht-wc.c: In function ‘cht_wc_extcon_get_charger’: include/linux/device.h:1420:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/extcon/extcon-intel-cht-wc.c:148:3: note: in expansion of macro ‘dev_warn’ dev_warn(ext->dev, ^~~~~~~~ drivers/extcon/extcon-intel-cht-wc.c:152:2: note: here case CHT_WC_USBSRC_TYPE_SDP: ^~~~ Signed-off-by: Andy Shevchenko Signed-off-by: Chanwoo Choi
