* drivers/mfd/rtsx_usb.c: export device tableJeff Mahoney2014-08-141-0/+1
| | | | | | | | | | | | | | | The rtsx_usb driver contains the table for the devices it supports but doesn't export it. As a result, no alias is generated and it doesn't get loaded automatically.

| | | | | | | | | | | | | | | | | | | | | | | | | | single-ulpi-bypass is a flag used for older OMAP3 silicon. The flag when set, can excite code that improperly uses the OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit. Instead it clears all of the other bits disabling all of the ports in the process.

| * mfd: arizona: Only free the CTRLIF_ERR IRQ if we requested itCharles Keepax2014-07-281-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | We only request the control interface error IRQ if we set ctrlif_error, as such we should only free it in that situation. Otherwise we will attempt to free an IRQ we never requested and get a warning from the IRQ core. This patch moves the ctrlif_error variable into the arizona structure and checks it in all cases we free the control interface error IRQ.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner A23 SoC has a PRCM unit like the previous A31 SoC. The differences are the AR100 clock can no longer be modified, the APB0 clock has different divisors, and some clock gates are gone. This patch adds a compatible with a modified subdevice list for the A23.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We know how many bytes the EC should be sending us (which is also the number of bytes transferred) and also how many bytes the EC actually wanted to send to us. When computing the checksum and copying back data let's make sure we take the lesser of the two of those. We'll also complain if the EC tried to send us too many bytes. The EC sending us too few bytes is legit for when we send the EC an invalid command. This is based on similar code in cros_ec_spi.
