2011-11-11plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desiredPaul Fertser1-5/+5
commit 6571534b600b8ca1936ff5630b9e0947f21faf16 upstream. 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.

2011-10-03MXC: iomux-v3: correct NO_PAD_CTRL definitionTroy Kisky1-1/+1
commit 425933b30b0ccfac58065bca6c853ea627443cdf upstream. iomux-v3.c uses NO_PAD_CTRL as a 32 bit value so it should not be shifted left by MUX_PAD_CTRL_SHIFT(41) Previously, anything requesting NO_PAD_CTRL would get their pad control register set to 0. Since it is a pad control mask, place it with the other mask values.

2011-05-19ARM: mx3: make ioremap quirk ready for multi-SoC kernelsUwe Kleine-König2-10/+17
To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image the ioremap quirk needs a runtime check. While touching this code make the comment more understandable by adding a sentence from the commit log that introduced it (eadefef ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)). As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which #includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros needs to be included before mach/mx27.h and mach/mx31.h.)

2011-05-19ARM: mx3: dynamically allocate "ipu-core" devicesUwe Kleine-König1-0/+18
... together with the related devices "mx3_camera" and "mx3_sdc_fb". "mx3_camera" doesn't fit the scheme of the other devices that just are allocated and registered in a single function because it needs additional care to get some dmaable memory. So currently imx31_alloc_mx3_camera duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's worth to split the latter to be able to reuse more code. This gets rid of mach-mx3/devices.[ch] and so several files need to be adapted not to #include devices.h anymore.

2011-05-07ARM: zImage: remove the static qualifier from global data variablesNicolas Pitre1-1/+1
To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols. This usually means that no global variables can be marked static unless they're also const. Let's remove the static qualifier from current offenders, or turn them into const variables when possible. Next commit will ensure the build fails if one of those is reintroduced due to otherwise enforced coding standards for the kernel.
