Subject: ARM: pxa: Add standard UART to hx4700_pin_config[]
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0de91b618281251beb9f73eaa436337779ae25f2;p=deliverable%2Flinux.git

ARM: pxa: Add standard UART to hx4700_pin_config[]

Add the two standard UART signals (GPIO46_STUART_RXD, GPIO47_STUART_TXD) to the
initial mfp config table hx4700_pin_config[] passed to pxa2xx_mfp_config().
Although pxa2xx_transceiver_mode() can subsequently set these two signals via
its own call to pxa2xx_mfp_config(), pxa2xx_transceiver_mode() is only present
when CONFIG_PXA_FICP=y. Hence this patch provides a default mfp config.
