From: Anton Vorontsov Date: Fri, 1 Oct 2010 14:23:24 +0000 (+0400) Subject: altera_uart: Make it possible to use Altera UART and 8250 ports together X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99793c660c811309ae4ca94cc9cf1c2f34940197;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git altera_uart: Make it possible to use Altera UART and 8250 ports together This fixes tty name, major and minor numbers. The major number 204 is used across many platform-specific serial drivers, so we use that.
