ARM: davinci: remove include/mach/ subdirectory

2022-04-29T07:53:06Z

The files in include/mach are only used from mach/davinci, so they are no longer needed in the traditional location. Move them to arch/arm/mach-davinci/ and drop the logic for the special include path. The mach/uncompress.h file is not used at all and can just be removed. Signed-off-by: Arnd Bergmann

ARM: davinci: serial.c: remove unused serial_read_reg()

2015-01-14T10:26:12Z

Remove function serial_read_reg() that is not used anywhere. This was partially found by using a static code analysis program called cppcheck. Signed-off-by: Rickard Strandqvist Signed-off-by: Sekhar Nori

ARM: davinci: serial: remove davinci_serial_setup_clk()

2013-08-21T19:08:59Z

Get rid of davinci_serial_setup_clk() since its not called from multiple places now. Instead initialize clock in davinci_serial_init() itself. This also helps get rid of "serial_dev" member of struct davinci_soc_info.

ARM: davinci: serial: get rid of davinci_uart_config

2013-08-21T19:08:59Z

"struct davinci_uart_config" was introduced to specify UART ports brought out or enabled on the board. But none of the boards use it for that purpose and we are not going to add anymore board files, so remove the structure.

ARM: davinci: uart: move to devid based clk_get

2013-07-22T10:04:55Z

For modules having single clock, clk_get should be done with dev_id. But current davinci implementation handles multiple instances of the UART devices with single platform_device_register. Hence clk_get is based on con_id rather than dev_id, this is not correct. Do platform_device_register for each instance and clk_get on dev_id.

ARM: davinci: serial: provide API to initialze UART clocks

2012-10-27T10:58:31Z

Provide an API to initialize a UART clock. Refactor existing davinci_serial_init() to separate out the part which enables the clock. This will later be used to help DA850 DT boot support. Signed-off-by: Sekhar Nori

ARM: davinci: convert platform code to use clk_prepare/clk_unprepare

2012-10-24T11:22:05Z

As a first step towards migrating davinci platforms to use common clock framework, replace all instances of clk_enable() with clk_prepare_enable() and clk_disable() with clk_disable_unprepare(). Until the platform is switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just adds a might_sleep() call and would work without any issues. This will make it easy later to switch to common clk based implementation of clk driver from DaVinci specific driver.

Davinci: serial - conditional reset via pwremu

2010-05-06T22:02:10Z

With this patch, AR7 type uart ports are not reset via pwremu registers. This allows davinci_serial_init() reuse on tnetv107x soc. Signed-off-by: Cyril Chemparathy Signed-off-by: Kevin Hilman

Davinci: serial - use ioremap()

2010-05-06T22:02:10Z

This patch implements davinci serial cleanups towards having this code reusable on tnetv107x. The change reuses the platform data membase field to hold the remapped space. By disabling the UPF_IOREMAP flag in the platform data, we prevent the 8250 driver from repeating the ioremap. Signed-off-by: Cyril Chemparathy Signed-off-by: Kevin Hilman
