Subject: [PATCH] mfd: at91-usart: Add platform dependency
Date: Mon, 12 Nov 2018 10:49:42 +0100 [thread overview]
Message-ID: <20181112104942.765456f7@endymion> (raw)
It doesn't make sense to present option MFD_AT91_USART by default if
not building an AT91 kernel, as the drivers which depend on it are
not available.

As a side note, maybe it would make sense to have SPI_AT91_USART
select MFD_AT91_USART instead of depend on it, so that
MFD_AT91_USART could be hidden?

Select this to get support for AT91 USART IP. This is a wrapper
over at91-usart-serial driver and usart-spi-driver. Only one function
