2011-10-25ARM: i.MX28: shift frac value in _CLK_SET_RATEMatt Burtch1-1/+1
Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to reset the clock divider for the SSP0 parent clock, in this case IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but when the new frac value is written the value isn't shifted up to write the correct bit-field. This results in IO0FRAC being set to 0 and CPUFRAC being corrupted. This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0 and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1. Tested on custom i.MX28 board with SSP0 SPI driver. Signed-off-by: Matt Burtch <matt@grid-net.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2011-10-25plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desiredPaul Fertser1-5/+5
To configure pads during the initialisation a set of special constants is used, e.g. #define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP) The problem is that no pull-up/down is getting activated unless both PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module enable) set. This is clearly stated in the i.MX25 datasheet and is confirmed by the measurements on hardware. This leads to some rather hard to understand bugs such as misdetecting an absent ethernet PHY (a real bug i had), unstable data transfer etc. This might affect mx25, mx35, mx50, mx51 and mx53 SoCs. It's reasonable to expect that if the pullup value is specified, the intention was to have it actually active, so we implicitly add the needed bits.

This fixes a bug where if trying to use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be affected by a changing SDMMC1_VDDS. Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever SDMMC1_VDDS ramps up/down or changes for cell protection purposes. MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore they can operate independently.

Apple Quad G5 has some oddity in it's device-tree which causes the new generic matching code to fail to relate nodes for PCI-E devices below U4 with their respective struct pci_dev. This breaks graphics on those machines among others. This fixes it using a quirk which copies the node pointer from the host bridge for the root complex, which makes the generic code work for the children afterward.

2011-09-29sparc64: Force the execute bit in OpenFirmware's translation entries.David S. Miller1-0/+5
In the OF 'translations' property, the template TTEs in the mappings never specify the executable bit. This is the case even though some of these mappings are for OF's code segment. Therefore, we need to force the execute bit on in every mapping. This problem can only really trigger on Niagara/sun4v machines and the history behind this is a little complicated. Previous to sun4v, the sun4u TTE entries lacked a hardware execute permission bit. So OF didn't have to ever worry about setting anything to handle executable pages. Any valid TTE loaded into the I-TLB would be respected by the chip. But sun4v Niagara chips have a real hardware enforced executable bit in their TTEs. So it has to be set or else the I-TLB throws an instruction access exception with type code 6 (protection violation). We've been extremely fortunate to not get bitten by this in the past. The best I can tell is that the OF's mappings for it's executable code were mapped using permanent locked mappings on sun4v in the past. Therefore, the fact that we didn't have the exec bit set in the OF translations we would use did not matter in practice. Thanks to Greg Onufer for helping me track this down. Signed-off-by: David S.

2011-09-26[S390] Do not clobber personality flags on execMartin Schwidefsky1-1/+2
Analog to git commit 59e4c3a2fe9cb1681bb2cff508ff79466f7585ba do not clear the additional personality flags on exec. We need to inherit the personality bits in PER_MASK across exec. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2011-09-26ARM: 7099/1: futex: preserve oldval in SMP __futex_atomic_opWill Deacon1-17/+17
The SMP implementation of __futex_atomic_op clobbers oldval with the status flag from the exclusive store. This causes it to always read as zero when performing the FUTEX_OP_CMP_* operation. This patch updates the ARM __futex_atomic_op implementations to take a tmp argument, allowing us to store the strex status flag without overwriting the register containing oldval.

2011-09-26ARM: dma-mapping: free allocated page if unable to mapRussell King1-0/+2
If the attempt to map a page for DMA fails (eg, because we're out of mapping space) then we must not hold on to the page we allocated for DMA - doing so will result in a memory leak.
