Subject: [PATCH] serial/bcm63xx_uart: use correct alias naming
|
||||
|
||||
The bcm63xx_uart driver uses the of alias for determing its id. Recent
|
||||
changes in dts files changed the expected 'uartX' to the recommended
|
||||
'serialX', breaking serial output. Fix this by checking for a 'serialX'
|
||||
alias as well.
|
||||
|
||||
Fixes: e3b992d028f8 ("MIPS: BMIPS: Improve BCM6328 device tree")
|
||||
Fixes: 2d52ee82b475 ("MIPS: BMIPS: Improve BCM6368 device tree")
|
||||
Fixes: 7537d273e2f3 ("MIPS: BMIPS: Add device tree example for BCM6358")
