2014-11-18can: m_can: update to support CAN FD featuresDong Aisheng
Bosch M_CAN is CAN FD capable device. This patch implements the CAN FD features include up to 64 bytes payload and bitrate switch function. 1) Change the Rx FIFO and Tx Buffer to 64 bytes for support CAN FD up to 64 bytes payload. It's backward compatible with old 8 bytes normal CAN frame. 2) Allocate can frame or canfd frame based on EDL bit 3) Bitrate Switch function is disabled by default and will be enabled according to CANFD_BRS bit in cf->flags.

2014-11-18can: m_can: add missing delay after setting CCCR_INIT bitDong Aisheng
The spec mentions there may be a delay until the value written to INIT can be read back due to the synchronization mechanism between the two clock domains. But it does not indicate the exact clock cycles needed. The 5us delay is a test value and seems ok. Without the delay, CCCR.CCE bit may fail to be set and then the initialization fail sometimes when do repeatly up and down.

2014-11-18can: m_can: add missing message RAM initializationDong Aisheng
The M_CAN message RAM is usually equipped with a parity or ECC functionality. But RAM cells suffer a hardware reset and can therefore hold arbitrary content at startup - including parity and/or ECC bits. To prevent the M_CAN controller detecting checksum errors when reading potentially uninitialized TX message RAM content to transmit CAN frames the TX message RAM has to be written with (any kind of) initial data.

2014-11-18of/base: Fix PowerPC address parsing hackBenjamin Herrenschmidt
We have a historical hack that treats missing ranges properties as the equivalent of an empty one. This is needed for ancient PowerMac "bad" device-trees, and shouldn't be enabled for any other PowerPC platform, otherwise we get some nasty layout of devices in sysfs or even duplication when a set of otherwise identically named devices is created multiple times under a different parent node with no ranges property. This fix is needed for the PowerNV i2c busses to be exposed properly and will fix a number of other embedded cases.

2014-11-18of: Fix crash if an earlycon driver is not foundKevin Cernekee
__earlycon_of_table_sentinel.compatible is a char[128], not a pointer, so it will never be NULL. Checking it against NULL causes the match loop to run past the end of the array, and eventually match a bogus entry, under the following conditions: - Kernel command line specifies "earlycon" with no parameters - DT has a stdout-path pointing to a UART node - The UART driver doesn't use OF_EARLYCON_DECLARE (or maybe the console driver is compiled out) Fix this by checking to see if match->compatible is a non-empty string.

2014-11-18arm64/mm: Remove hack in mmap randomize layoutYann Droneaud
Since commit 8a0a9bd4db63 ('random: make get_random_int() more random'), get_random_int() returns a random value for each call, so comment and hack introduced in mmap_rnd() as part of commit 1d18c47c735e ('arm64: MMU fault handling and page table management') are incorrects. Commit 1d18c47c735e seems to use the same hack introduced by commit a5adc91a4b44 ('powerpc: Ensure random space between stack and mmaps'), latter copied in commit 5a0efea09f42 ('sparc64: Sharpen address space randomization calculations.'). But both architectures were cleaned up as part of commit fa8cbaaf5a68 ('powerpc+sparc64/mm: Remove hack in mmap randomize layout') as hack is no more needed since commit 8a0a9bd4db63. So the present patch removes the comment and the hack around get_random_int() on AArch64's mmap_rnd(). Cc: David S.

2014-11-18mfd/axp20x: avoid irq numbering collisionJacob Pan
IRQ numbers in axp20x devices are defined with high-order bit first in each IRQ enable/status registers. On Intel platforms it is more common to number IRQs with least significant bit first. Therefore, sharing IRQ# between the two is very difficult. Since AXP288 is a customized PMIC for Intel platform and the amount of shared IRQs are very small, we use separate IRQ numbering. This also fixes collision and a duplicate in WBTO interrupt. e.g. For the 16 interrupts controlled in IRQ enabled registers 1 & 2, on axp20x for ARM, the PMIC local IRQ numbers and register bits are mapped as: IRQ#: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 --------------------------------------------------------- ARM: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 Intel: 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
