|/ | | | | | | | | | | | | | | | | | | | | | | Make the map match the reality, the current binding text is nonsense: - The clock required for the clocking of the serial port must come first and is not optional (as the driver will otherwise proceed to grab and use the apb_pclk as uartclk), and the apb_pclk that clocks the logic must come second as the code will retrieve the first clock by index, whereas the PrimeCell but will explicitly look for "apb_pclk" so this can be specified later, as it is looked up by name. - The pin control state "default" is the only mandated state, the sleep state is entirely optional. We also add an example to avoid further confusion.

* Revert "serial: uart: add hw flow control support configuration"Peter Hurley2014-09-081-1/+0
| | | | | | | | | | | | | | | | | | | | This reverts commit 06aa82e498c144c7784a6f3d3b55458b272d6146. This commit purports to enable auto CTS flow control for the 8250 UART driver. However, the 8250 UART driver already supports auto CTS flow control via UART_CAP_AFE and UART_CAP_EFR. Indeed, this patch introduces another DT attribute for which an existing firmware flag already exists ("auto-flow-control"). Furthermore, the use of UPF_HARD_FLOW requires the UART driver to define .throttle and .unthrottle methods, neither of which are defined for the 8250 UART driver (which will result in a NULL ptr dereference). Finally, this patch supposes to fix existing bugs in the serial core for auto CTS-enabled hardware, but does not include the class of hardware for which these bugs exist.

| | | | | | | | | | | | | | CLPS711X serial driver uses the system wide registers to control the modem signals. Now gpio-syscon driver can be used for this purposes. mctrl_gpio helpers allow us to create GPIO bindings for any of modem/tty control signals that extends the functionality of the driver. This patch makes such change. This change does not break any current DT bindings, since DT support for this platform is not introduced yet.

Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...

| | | | | | | | | | | | | | | | | | | | | | 8250 uart driver currently supports only software assisted hw flow control. The software assisted hw flow control maintains a hw_stopped flag in the tty structure to stop and start transmission and use modem status interrupt for the event to drive the handshake signals. This is not needed if hw has flow control capabilities. This patch adds a DT attribute for enabling hw flow control for a uart port. Also skip stop and start if this flag is present in flag field of the port structure.

| | * ARM/serial: at91: switch atmel serial to use gpiolibLinus Walleij2013-12-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This passes the errata fix using a GPIO to control the RTS pin on one of the AT91 chips to use gpiolib instead of the AT91-specific interfaces. Also remove the reliance on compile-time #defines and the cpu_* check and rely on the platform passing down the proper GPIO pin through platform data. This is a prerequisite for getting rid of the local GPIO implementation in the AT91 platform and move toward multiplatform. The patch also adds device tree support for getting the RTS GPIO pin from the device tree on DT boot paths.

So add an appropriate namespace and fall back to the generic name in case of failure.
