2019-04-11dma: ti: add driver to K3 UDMAVignesh R
The UDMA-P is intended to perform similar (but significantly upgraded) functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P module supports the transmission and reception of various packet types. The UDMA-P also supports acting as both a UTC and UDMA-C for its internal channels. Channels in the UDMA-P can be configured to be either Packet-Based or Third-Party channels on a channel by channel basis. The initial driver supports: - MEM_TO_MEM (TR mode) - DEV_TO_MEM (Packet mode) - MEM_TO_DEV (Packet mode) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Vignesh R <vigneshr@ti.com>

2019-04-11soc: ti: k3: add navss ringacc driverGrygorii Strashko
The Ring Accelerator (RINGACC or RA) provides hardware acceleration to enable straightforward passing of work between a producer and a consumer. There is one RINGACC module per NAVSS on TI AM65x SoCs. The RINGACC converts constant-address read and write accesses to equivalent read or write accesses to a circular data structure in memory. The RINGACC eliminates the need for each DMA controller which needs to access ring elements from having to know the current state of the ring (base address, current offset). The DMA controller performs a read or write access to a specific address range (which maps to the source interface on the RINGACC) and the RINGACC replaces the address for the transaction with a new address which corresponds to the head or tail element of the ring (head for reads, tail for writes). Since the RINGACC maintains the state, multiple DMA controllers or channels are allowed to coherently share the same rings as applicable. The RINGACC is able to place data which is destined towards software into cached memory directly. Supported ring modes: - Ring Mode - Messaging Mode - Credentials Mode - Queue Manager Mode TI-SCI integration: Texas Instrument's System Control Interface (TI-SCI) Message Protocol now has control over Ringacc module resources management (RM) and Rings configuration. The Ringacc driver manages Rings allocation by itself now and requests TI-SCI firmware to allocate and configure specific Rings only. It's done this way because, Linux driver implements two stage Rings allocation and configuration (allocate ring and configure ring) while TI-SCI Message Protocol supports only one combined operation (allocate+configure).

2018-12-06mtd: Don't stop MTD partition creation when it fails on one deviceBoris Brezillon
MTD partition creation code is a bit tricky. It tries to figure out when things have changed (either MTD dev list or mtdparts/mtdids vars) and when that happens it first deletes all the partitions that had been previously created and then creates the new ones based on the new mtdparts/mtdids values. But before deleting the old partitions, it ensures that none of the currently registered parts are being used and bails out when that's not the case. So, we end up in a situation where, if at least one MTD dev has one of its partitions used by someone (UBI for instance), the partitions update logic no longer works for other devs. Rework the code to relax the logic and allow updates of MTD parts on devices that are not being used (we still refuse to updates parts on devices who have at least one of their partitions used by someone).

2018-12-05time: Update mdelay() to delay in one large chunkSimon Glass
The current function delays in one millisecond at a time. This does not work well on sandbox since it results in lots of calls to usleep(1000) in a tight loop. This makes the sleep duration quite variable since each call results in a sleep of *at least* 1000us, but possibly more. Depending on how busy the machine is, the sleep time can change quite a bit. We cannot fix this in general, but we can reduce the effect by doing a single sleep. The multiplication works fine with an unsigned long argument up until a sleep time of about 4m milliseconds. This is over an hour and we can be sure that delays of that length are not useful. Update the mdelay() function to call udelay() only once with the calculated delay value.

2018-12-02efi_loader: PSCI reset and shutdownHeinrich Schuchardt
When an operating system started via bootefi tries to reset or power off this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or an SMC command has to be issued. The current implementation always uses SMC. This results in crashes on systems where the PSCI firmware is implemented in the hypervisor, e.g. qemu-arm64_defconfig. The logic to decide which call is needed based on the device tree is already implemented in the PSCI firmware driver. During the EFI runtime the device driver model is not available. But we can minimize code duplication by merging the EFI runtime reset and poweroff code with the PSCI firmware driver. As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff and reset_misc routines let's move them into the same code module.
