Fabien Parent	70dbbd7269	mmc: mtk-sd: fix SPL compilation when GPIO=y and SPL_GPIO=n ... It is not possible to link the SPL image when CONFIG_GPIO is enabled but CONFIG_SPL_GPIO is not. Use the IS_ENABLED macro instead to correctly check whether CONFIG_{SPL_}GPIO is enabled. This commit fixes the following errors: * undefined reference to `dm_gpio_get_value * undefined reference to `gpio_request_by_name' Signed-off-by: Fabien Parent <fparent@baylibre.com> [trini: Move guard to fix warning in msdc_ops_get_wp()] Signed-off-by: Tom Rini <trini@konsulko.com>	2019-01-26 08:13:54 -05:00
Fabien Parent	924ed344a7	mmc: mtk-sd: fix possible incomplete read ops ... The code is checking for incomplete read when it see the INT_XFER_COMPL flag, but it forget to first check whether there is anything left in the FIFO to copy to the RX buffer. This means that sometimes we will get errors because of erroneous incomplete read operation. This commit fixes the driver re-ordering the code so that we first check for data inside the RX fifo and only after check the status of the INT_XFER_COMPL flag.
