This patch series adds a serial driver to handle uarts on omap platforms. Currenlty omap-uarts are handled with 8250 driver, since updating this driver with omap specific features will over load the 8250 driver with all omap-specific data thus a new driver is added to configure and support features like dma, h/w, s/w flowcontrol for omap-uarts. Also the patch series updates various low level platform specific serial data to support omap-uarts with hwmod framework and adds support for uart4 on OMAP3630. Patch series applies cleanly on pm-core branch on kevins PM tree. http://git.kernel.org/?p=linux/kernel/git/khilman/linux-omap-pm.git; a=shortlog;h=refs/heads/pm-core Patch series Testing Status Update: ----------------------------------- OMAP4:(SDP): Boot tested with ttyO* and ttyS* interfaces using this patch series. OMAP2(2430SDP): Boot tested with ttyO* and ttyS* interfaces using this patch series. (Couldn't test pm functionality here due to board shortage). OMAP3:(3430/3630SDP, ZOOM2/3): Boot tested for console with ttyS* and ttyO* interfaces. PM functionality checked omap3: 1) ret count: debugfs mounted sleep_while_idle enabled, checked for ret count values to increment this was done by setting sysfs timeout for all uarts. Also checked by unsetting uart sysfs timeout to check ret count stopped incrementing. 2) core off count: debugfs mounted sleep_while_idle and enable_off_mode enabled checked for core_off count to increment for core/per_pwrdm. 3) Susupend: Done using echo mem > /sys/power/state. Ensured no difference in behaviour with and without this patch series. v2 to v3 changes: ----------------- 1) Minor changes with omap-serial https://patchwork.kernel.org/patch/199652/ 2) Undo the timeout macro modification done by mistake. https://patchwork.kernel.org/patch/199642/ 3) update description log for patch: OMAP3: SERIAL: Initialize all omap-uarts for zoom boards https://patchwork.kernel.org/patch/199672/ v1 to v2 changes: ----------------- 1) Incorporate timeout check http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg35106.html 2) Add wk_st, padconf etc for uart4 http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg35105.html Benoit Cousson (1): OMAP4: UART: Add uart1-4 hwmods data for omap4 Govindraj.R (8): OMAP2: UART: remove set_uart_globals.
