* dm: serial: use Driver Model for UniPhier serial driverMasahiro Yamada2014-10-23-136/+172
| | | | | | | | | | | | | | | | | This commit converts UniPhier on-chip serial driver to driver model. Since UniPhier SoCs do not have Device Tree support, some board files should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories. (Device Tree support for UniPhier platform is still under way.) Now the base address and master clock frequency are passed from platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and CONFIG_SYS_UNIPHIER_UART_CLK should be removed. Tested on UniPhier PH1-LD4 ref board. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | Commit b8893327e9d2 (dm: serial: Put common code into separate functions) consolidated getc() and putc(). This commit does more puts() and tsts(). Also rename locally used functions to _serial_*() for clarification because we have similar functions names here are there in this file.

| | | | | | | | | | Commit b8893327e9d2 (dm: serial: Put common code into separate functions) consolidated getc() correctly, but introduced another bug to putc(); serial_stub_putc() passes sdev->priv to serial_putc_dev(), but serial_putc_dev() uses cur_dev instead of the given argument.

* serial: add static directive to local functionsMasahiro Yamada2014-10-23-26/+12
| | | | | | | | | | | | The functions _serial_putc, _serial_putc_raw, _serial_puts, _serial_getc, _serial_tstc, _serial_setbrg are defined and used locally in each of serial_ns16550.c and serial_s3c24x0.c.

* dm: move platform data headers to include/dm/platform_dataMasahiro Yamada2014-10-23-3/+3
| | | | | | | | | | | | | | | | | | 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>

| | | | | | | | To permit information to be passed from the early U-Boot code to board_init_f() we cannot zero the global_data in board_init_f(). Instead zero it in the start-up code. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | We have several GPIO drivers now and all are doing similar things to record which GPIOs are reserved. Move this logic into the uclass to make the drivers similar.

| | | | | | | | | | | | | | | | | | | | | With these options in place it is not possible to change the serial port using 'make menuconfig' or similar. It seems to result in duplicate defines. For example: In file included from include/linux/kconfig.h:4:0, from <command-line>:0: include/generated/autoconf.h:20:0: note: this is the location of the previous definition #define CONFIG_CONS_INDEX 2 ^ The default option seems to be 1 anyway, in board/ti/am335x/Kconfig.
