serial: altera_uart: call iounmap() at driver remove

2017-05-25T12:36:37Z

The driver calls ioremap() in the probe function but doesn't call iounmap() in the remove function correspondingly. Do so now. Follow commit 5c9d6abed9e0 ("serial: altera_jtaguart: adding iounmap()") Cc: Alexey Khoroshilov Signed-off-by: Tobias Klauser Signed-off-by: Greg Kroah-Hartman

serial: altera_uart: add earlycon support

2017-03-31T14:56:10Z

Nios2 currently uses its own early printk implementation, rather than using unified earlycon support to show boot messages on altera_uart. Add earlycon support to altera_uart so that other archs may use it. Also, this (together with the corresponding patch for altera_jtaguart) will allow the early printk implementation in arch/nios2 to be removed in a future patch.

serial: altera: constify uart_ops structures

2016-09-02T13:01:16Z

Check for uart_ops structures that are only stored in the ops field of a uart_port structure. This field is declared const, so uart_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct uart_ops i@p = { ... }; @ok@ identifier r.i; struct uart_port e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct uart_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct uart_ops i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Tobias Klauser Signed-off-by: Greg Kroah-Hartman

serial: altera_uart: Use of_property_read_u32 instead of open-coding it

2015-10-04T16:47:49Z

Use of_property_read_u32 instead of of_get_property with return value checks and endianness conversion. Also remove the !CONFIG_OF implementation of altera_uart_get_of_uartclk as of_property_read_u32 will return a non-zero value for !CONFIG_OF.

serial: altera: Adopt uart_console_write()

2014-07-12T00:49:46Z

This driver does not currently use uart_console_write() and instead provides is own LF to LFCR conversion in it's console_write() method. We should use the library function instead.
