pch_uart: Add uart_clk selection for the MinnowBoard

2013-07-22T01:21:23Z

commit 29692d05647cb7ecea56242241f77291d5624b95 upstream. Use DMI_BOARD_NAME to determine if we are running on a MinnowBoard and set the uart clock to 50MHz if so. This removes the need to pass the user_uartclk to the kernel at boot time. Signed-off-by: Darren Hart Cc: Jiri Slaby Cc: "H.

Revert "serial: 8250_pci: add support for another kind of NetMos Technology PCI 9835 Multi-I/O Controller"

2013-07-13T18:42:26Z

commit 828c6a102b1f2b8583fadc0e779c46b31d448f0b upstream. This reverts commit 8d2f8cd424ca0b99001f3ff4f5db87c4e525f366. As reported by Stefan, this device already works with the parport_serial driver, so the 8250_pci driver should not also try to grab it as well.

parisc: fix serial ports on C8000 workstation

2013-06-18T18:29:07Z

The C8000 workstation (64 bit kernel only) has a somewhat different serial port configuration than other models. Thomas Bogendoerfer sent a patch to fix this in September 2010, which was now minimally modified by me. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Helge Deller

Revert "serial: 8250: Make SERIAL_8250_RUNTIME_UARTS work correctly"

2013-06-03T17:08:28Z

This reverts commit cfcec52e9781f08948c6eb98198d65c45be75a70. This regresses a longstanding behaviour on X86 systems, which end up with PCI serial ports moving between ttyS4 and ttyS0 when you bisect to opposite sides of this commit, resulting in the need to constantly modify the console setting in order to bisect across it. Please revert, we can work on solving this for ARM platforms in a less disruptive way. Signed-off-by: Kyle McMartin Cc: Karthik Manamcheri Signed-off-by: Greg Kroah-Hartman

Pull ARM SoC fixes from Olof Johansson: "We didn't have any fixes sent up for -rc2, so this is a slightly larger batch. A bit all over the place platform-wise; OMAP, at91, marvell, renesas, sunxi, ux500, etc. I tried to summarize highlights but there isn't a whole lot to point out. Lots of little things fixed all over. A couple of defconfig updates due to new/changing options." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (44 commits) ARM: at91/sama5: fix incorrect PMC pcr div definition ARM: at91/dt: fix macb pinctrl_macb_rmii_mii_alt definition ARM: at91: at91sam9n12: move external irq declatation to DT ARM: shmobile: marzen: Use error values in usb_power_* ARM: tegra: defconfig fixes ARM: nomadik: fix IRQ assignment for SMC ethernet ARM: vt8500: Add missing NULL terminator in dt_compat clk: tegra: add ac97 controller clock clk: tegra: remove USB from clk init table ARM: dts: mvebu: Fix wrong the address reg value for the L2-cache node ARM: plat-orion: Fix num_resources and id for ge10 and ge11 ARM: OMAP2+: hwmod: Remove sysc slave idle and auto idle apis SERIAL: OMAP: Remove the slave idle handling from the driver ARM: OMAP2+: serial: Remove the un-used slave idle hooks ARM: OMAP2+: hwmod-data: UART IP needs software control to manage sidle modes ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in active ARM: OMAP2+: hwmod: Fix sidle programming in _enable_sysc()/_idle_sysc() arm: mvebu: fix the 'ranges' property to handle PCIe ARM: mvebu: select ARCH_REQUIRE_GPIOLIB for mvebu platform ARM: AM33XX: Add missing .clkdm_name to clkdiv32k_ick clock ...
