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.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2016-07-21serial_mxc: Remove unconditional DCE settingBreno Lima
Commit 83fd908f28c ("dm: imx: serial: Support DTE mode when using driver model") breaks the serial output for the imx boards that do not use the serial driver model. The reason for the breakage is that it's setting UFCR_DCEDTE unconditionally for the non-dm case. So keep the original behavior by removing UFCR_DCEDTE setting in the non-dm case. Tested on mx7sabresd and mx6wandboard. Signed-off-by: Breno Lima <breno.lima@nxp.com> Acked-by: Stefan Agner <stefan.agner@toradex.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com>
2016-07-19dm: imx: serial: Support DTE mode when using driver modelStefan Agner
The MXC UART IP can be run in DTE or DCE mode. This depends on the board wiring and the pinmux used and hence is board specific. This extends platform data with a new field to choose wheather DTE mode shall be used. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-03-14serial: Move carriage return before line feed for some serial driversAlison Wang
In general, a carriage return needs to execute before a line feed. The patch is to change some serial drivers based on this rule, such as serial_mxc.c, serial_pxa.c, serial_s3c24x0.c and usbtty.c. Signed-off-by: Alison Wang <alison.wang@nxp.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-01-03serial_mxc: Fix setup of UARTx_UFCR registerMaximilian Schwerin
This patch writes the default values for TXTL and RXTL to UARTx_UFCR. Without this patch some older kernel versions crash as UARTx_UFCR was not always correctly initialized. Signed-off-by: Maximilian Schwerin <maximilian.schwerin@tigris.de>
2014-10-23dm: move platform data headers to include/dm/platform_dataMasahiro Yamada
The platform_data definitions are generally referenced from both drivers and board files. That is why header files defining platform_data sturectures are placed in "include" directory, but our top level "include" directory is already too cluttered. Let's collect platform_data definitions under the directory "include/dm/platform_data" like Linux gathers ones around under "include/linux/platform_data". This commit moves two header files: include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h include/serial_pl01x.h -> include/dm/platform_data/serial_pl01x.h Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-05-28serial_mxc: disable new features of autobaud detectionEric Nelson
Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x reference manuals as follows: Autobaud Detection Not Improved-. Disables new features of autobaud detection (See Baud Rate Automatic Detection Protocol, for more details). 0 Autobaud detection new features selected 1 Keep old autobaud detection mechanism On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features" occasionally cause the receiver to get out of sync and continuously produce received characters of '\xff'. This patch disables the "new feature" on all boards, since there's no support for auto-baud in U-Boot on any of them.

2012-10-17serial: Use default_serial_puts() in driversMarek Vasut

2012-10-15serial: Remove CONFIG_SERIAL_MULTI from serial driversMarek Vasut

2012-10-15serial: arm: Implement CONFIG_SERIAL_MULTI into mxc serial driverMarek Vasut
Implement support for CONFIG_SERIAL_MULTI into mxc serial driver. This driver was so far only usable directly, but this patch also adds support for the multi method. This allows using more than one serial driver alongside the mxc driver. Also, add a weak implementation of default_serial_console() returning this driver.

2011-12-06MX: serial_mxc: cleanup removing nasty #ifdefStefano Babic
The serial driver for iMX SOCs is continuosly changed if a new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port> defines were used only to find the base address for the selected UART. Instead of that, move the base address to the board configuration file and drop all #ifdef from driver.

2011-04-27IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic
As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.
