Here is another fixes series for AT91 designed for 3.4-rc. We experienced some issues while compiling some drivers as modules: Joachim has corrected several of them. We may reduce this number of exported values by reworking some drivers, in the future. Some drivers are also modified here, I would like to keep them in the series as the modifications are really related with our recent move to irqdomains or simply related with compiler annotations. I keep dmaengine Kconfig modification in this "fixes" series. The DMA driver will not be available for 9x5 SoC family otherwise. * tag 'at91-fixes' of git://github.com/at91linux/linux-at91: dmaengine: Kconfig: fix Atmel at_hdmac entry USB: gadget/at91_udc: add gpio_to_irq() function to vbus interrupt USB: ohci-at91: change annotations for probe/remove functions leds-atmel-pwm.c: Make pwmled_probe() __devinit ARM: at91: fix at91sam9261ek Ethernet dm9000 irq ARM: at91: fix rm9200ek flash size ARM: at91: remove empty at91_init_serial function ARM: at91: fix typo in at91_pmc_base assembly declaration ARM: at91: Export at91_matrix_base ARM: at91: Export at91_pmc_base ARM: at91: Export at91_ramc_base ARM: at91: Export at91_st_base

2012-04-18ARM: OMAP1: DMTIMER: fix broken timer clock source selectionPaul Walmsley1-2/+2
DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src() tries to use __raw_{read,write}l() to read from and write to physical addresses, but those functions take virtual addresses. sparse caught this: arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:50:13: got unsigned int arch/arm/mach-omap1/timer.c:52:9: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:52:9: got unsigned int Fix by using omap_{read,writel}(), just like the other users of the MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term, removing omap_{read,write}l() is the appropriate thing to do; but this will take some work to do this cleanly. Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion to platform devices) that dangerously moved code and changed it in the same patch.

2012-04-17ARM: OMAP: serial: Fix the ocp smart idlemode handling bugSantosh Shilimkar1-1/+7
The current serial UART code, while fidling with ocp idlemode bits, forget about the smart idle wakeup bit even if it is supported by UART IP block. This will lead to missing the module wakeup on OMAP's where the smart idle wakeup is supported. This was the root cause of the console sluggishness issue, I have been observing on OMAP4 devices and also can be potential reason for some other UART wakeup issues.

2012-04-17ARM: OMAP2+: UART: Fix incorrect population of default uart padsGovindraj.R1-116/+0
Commit (7496ba3 ARM: OMAP2+: UART: Add default mux for all uarts) wrongly added muxing of default pads for all uarts. This causes breakage on multiple boards using uart pins for alternate functions. For example, on zoom3 random oopses can be seen with nfsroot as the smsc911x ethernet FIFO timings on GPMC bus are controlled by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these pads to uart4 functionality as commit 7496ba3 was doing. Not all boards tend to use all uarts and most of unused uart pins are muxed for other purpose. This commit breaks the modules which where trying to use unused uart pins on their boards. So remove the default pad muxing. Note that this is not a complete fix, as we now rely on bootloader set muxing for the uart wake-up events. Further patching is needed to enable wake-up events for uarts that are already muxed to uart mode.

2012-04-16ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEEJonathan Austin1-0/+12
Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE register states are not saved/restored at context switch. The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

2012-04-16ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpusLinus Walleij1-1/+5
During booting of cpu1, there is a short window where cpu1 is online, but not active where cpu1 is occupied by waiting to become active. If cpu0 then decides to schedule something on cpu1 and wait for it to complete, before cpu0 has set cpu1 active, we have a deadlock. Typically it's this CPU frequency transition that happens at this time, so let's just not wait for it to happen, it will happen whenever the CPU eventually comes online instead.

The atmel_mxt_ts driver has been extended to support more 'configuration objects' in commit 81c88a711 ("Input: atmel_mxt_ts - update object list"), what broke the configuration values for NURI board. These values are optional anyway, so remove them to get the driver working correctly.

2012-04-13ARM: OMAP2/3: VENC hwmods: Remove OCPIF_SWSUP_IDLE flag from VENC slave ↵Archit Taneja3-3/+0
interface The clocks for all DSS slave interfaces were recently changed to "dss_ick" on OMAP2 and OMAP3, this clock can be autoidled by PRCM. The VENC interface previously had "dss_54m_fck" as it's clock which couldn't be autoidled, and hence the OCPIF_SWSUP_IDLE flag was needed. Remove the OCPIF_SWSUP_IDLE flag from VENC interfaces as it's clock is now "dss_ick". This allows the PRCM hardware to autoidle the VENC interface clocks when they are not active, rather than relying on the software to do it, which can keep the interface clocks active unnecessarily.

wait for reset status" This reverts commit f9a2f9c3fa76eec55928e8e06f3094c8f01df7cb. This commit caused a regression in the I2C hwmod reset on OMAP2/3/4, logging messages similar to these during boot: [ 0.200378] omap_hwmod: i2c1: softreset failed (waited 10000 usec) [ 0.222076] omap_hwmod: i2c2: softreset failed (waited 10000 usec) While the original patch was intended to fix some reset-related timing issues, it's believed that these problems were actually fixed by commit 2800852a079504f35f88e44faf5c9c96318c0cca ("ARM: OMAP2+: hwmod: Restore sysc after a reset"): http://marc.info/?l=linux-arm-kernel&m=133410322617245&w=2 Cc: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-04-13ARM: OMAP2+: hwmod: add softreset delay field and OMAP4 dataFernando Guzman Lugo3-1/+15
Due to HW limitation, some IPs should not be accessed just after a softreset. Since the current hwmod sequence is accessing the sysconfig register just after the reset, it might lead to OCP bus error in that case. Add a new field in the sysconfig structure to specify a delay in usecs needed after doing a softreset. In the case of the ISS and FDIF modules, the L3 OCP port will be disconnected upon a SW reset. That issue was confirmed with HW simulation and an errata should be available soon. The HW recommendation to avoid that is to wait for 100 OCP clk cycles, before accessing the IP. Considering the worse case (OPP50), the L3 bus will run at 100 MHz, so a 1 usec delay is needed. Add an x2 margin to be safe.
