2017-07-26serial: stm32x7: add clk_get_rate() supportPatrice Chotard
Replace proprietary clock_get() by clk_get_rate() The stm32x7 serial driver is now "generic" and can be used by other STM32 SoCs. Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Acked-by: Vikas MANOCHA <vikas.manocha@st.com>
2017-07-26serial: stm32x7: migrate serial struct to driverPatrice Chotard
This allow to remove include/dm/platform_data/serial_stm32x7.h which was included in the past by stm32x7 driver and by stm32f746-disco.c board file. Since patch 42bf5e7c27 "serial: stm32f7: add device tree support" this file is no more needed in board file.

2017-06-12serial: stm32x7: simplify baud rate register calculationPatrice Chotard
Simplify baud rate register formula and use the oversampling uart feature. This code is aligned with what is implemented in kernel driver drivers/tty/serial/stm32-usart.c since kernel v4.9.

2017-06-12serial: stm32x7: align compatible with kernel onePatrice Chotard
stm32x7.c driver is dedicated for STM32F7. In kernel, "st,stm32-usart" and "st,stm32-uart" compatible strings are dedicated for STM32F4. To keep U-boot and kernel aligned, replace the serial compatible string from "st,stm32-usart", "st,stm32-uart" to "st,stm32f7-usart", "st,stm32f7-uart" specific for STM32F7.

With overrun enabled, serial port console freezes & stops receiving data with overun error if we keep sending data. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.
