2020-10-08spi: dw: Discard chip enabling on DMA setup errorSerge Semin
It's pointless to enable the chip back if the DMA setup procedure fails, since we'll disable it on the next transfer anyway. For the same reason We don't do that in case of a failure detected in any other methods called from the transfer_one() method. While at it consider any non-zero value returned from the dma_setup callback to be erroneous as it's supposed to be in the kernel.

2020-10-08spi: dw: Unmask IRQs after enabling the chipSerge Semin
It's theoretically erroneous to enable IRQ before the chip is turned on. If IRQ handler gets executed before the chip is enabled, then any data written to the Tx FIFO will be just ignored. I say "theoretically" because we haven't noticed any problem with that, but let's fix it anyway just in case...

2020-10-08spi: dw: Perform IRQ setup in a dedicated functionSerge Semin
In order to make the transfer_one() callback method more readable and for unification with the DMA-based transfer, let's detach the IRQ setup procedure into a dedicated function. While at it rename the IRQ-based transfer handler function to be dw_spi-prefixe and looking more like the DMA-related one.

2020-10-08spi: dw: Refactor IRQ-based SPI transfer procedureSerge Semin
Current IRQ-based SPI transfer execution procedure doesn't work well at the final stage of the execution. If all the Tx data is sent out (written to the Tx FIFO) but there is some data left to receive, the Tx FIFO Empty IRQ will constantly happen until all of the requested inbound data is received. Though for a short period of time, but it will make the system less responsive. In order to fix that let's refactor the SPI transfer execution procedure by taking the Rx FIFO Full IRQ into account. We'll read and write SPI transfer data each time the IRQ happens as before. If all the outbound data is sent out, we'll disable the Tx FIFO Empty IRQ. If there is still some data to receive, we'll adjust the Rx FIFO Threshold level, so the next IRQ would be raised at the moment of all incoming data being available in the Rx FIFO.

2020-10-08spi: dw: Refactor data IO procedureSerge Semin
The Tx and Rx data write/read procedure can be significantly simplified by using Tx/Rx transfer lengths instead of the end pointers. By having the Tx/Rx data leftover lengths (in the number of transfer words) we can get rid of all subtraction and division operations utilized here and there in the tx_max(), rx_max(), dw_writer() and dw_reader() methods. Such modification will not only give us the more optimized IO procedures, but will make the data IO methods much more readable than before.

2020-10-08spi: dw: Add DW SPI controller config structureSerge Semin
DW APB SSI controller can be used by the two SPI core interfaces: traditional SPI transfers and SPI memory operations. The controller needs to be accordingly configured at runtime when the corresponding operations are executed. In order to do that for the both interfaces from a single function we introduce a new data wrapper for the transfer mode, data width, number of data frames (for the automatic data transfer) and the bus frequency. It will be used by the update_config() method to tune the DW APB SSI up. The update_config() method is made exported to be used not only by the DW SPI core driver, but by the glue layer drivers too. This will be required in a coming further commit.

2020-10-08spi: dw: Update Rx sample delay in the config functionSerge Semin
Rx sample delay can be SPI device specific, and should be synchronously initialized with the rest of the communication and peripheral device related controller setups. So let's move the Rx-sample delay setup into the DW APB SSI configuration update method.

2020-10-08spi: dw: Simplify the SPI bus speed config procedureSerge Semin
The code currently responsible for the SPI communication speed setting up is a bit messy. Most likely for some historical reason the bus frequency is saved in the peripheral chip private data. It's pointless now since the custom communication speed is a SPI-transfer-specific thing and only if there is no SPI transfer data specified (like during the SPI memory operations) it can be taken from the SPI device structure. But even in the later case there is no point in having the clock divider and the SPI bus frequency saved in the chip data, because the controller can be used for both SPI-transfer-based and SPI-transfer-less communications. From software point of view keeping the current clock divider in an SPI-device specific storage may give a small performance gain (to avoid sometimes a round-up division), but in comparison to the total SPI transfer time it just doesn't worth saving a few CPU cycles in comparison to the total SPI transfer time while having the harder to read code. The only optimization, which could worth preserving in the code is to avoid unnecessary DW SPI controller registers update if it's possible. So to speak let's simplify the SPI communication speed update procedure by removing the clock-related fields from the peripheral chip data and update the DW SPI clock divider only if it's really changed. The later change is reached by keeping the effective SPI bus speed in the internal DW SPI private data.

2020-10-08spi: dw: Update SPI bus speed in a config functionSerge Semin
The SPI bus speed update functionality will be useful in another parts of the driver too (like to implement the SPI memory operations and from the DW SPI glue layers). Let's move it to the update_cr0() method then and since the later is now updating not only the CTRLR0 register alter its prototype to have a generic function name not related to CR0. Leave the too long line with the chip->clk_div setting as is for now, since it's going to be changed later anyway.

2020-10-08spi: dw: Detach SPI device specific CR0 config methodSerge Semin
Indeed there is no point in detecting the SPI peripheral device parameters and initializing the CR0 register fields each time an SPI transfer is executed. Instead let's define a dedicated CR0 chip-data member, which will be initialized in accordance with the SPI device settings at the moment of setting it up. By doing so we'll finally make the SPI device chip_data serving as it's supposed to - to preserve the SPI device specific DW SPI configuration. See spi-fsl-dspi.c, spi-pl022.c, spi-pxa2xx.c drivers for example of the way the chip data is utilized.

2020-10-08spi: dw: Add DWC SSI capabilitySerge Semin
Currently DWC SSI core is supported by means of setting up the core-specific update_cr0() callback. It isn't suitable for multiple reasons. First of all having exported several methods doing the same thing but for different chips makes the code harder to maintain. Secondly the spi-dw-core driver exports the methods, then the spi-dw-mmio driver sets the private data callback with one of them so to be called by the core driver again. That makes the code logic too complicated. Thirdly using callbacks for just updating the CR0 register is problematic, since in case if the register needed to be updated from different parts of the code, we'd have to create another callback (for instance the SPI device-specific parameters don't need to be calculated each time the SPI transfer is submitted, so it's better to pre-calculate the CR0 data at the SPI-device setup stage). So keeping all the above in mind let's discard the update_cr0() callbacks, define a generic and static dw_spi_update_cr0() method and create the DW_SPI_CAP_DWC_SSI capability, which when enabled would activate the alternative CR0 register layout. While at it add the comments to the code path of the normal DW APB SSI controller setup to make the dw_spi_update_cr0() method looking coherent.

2020-10-08crypto: bcm - Verify GCM/CCM key length in setkeyHerbert Xu
The setkey function for GCM/CCM algorithms didn't verify the key length before copying the key and subtracting the salt length. This patch delays the copying of the key til after the verification has been done. It also adds checks on the key length to ensure that it's at least as long as the salt.

2020-10-07drm/amdgpu: fix NULL pointer dereference for RenoirDirk Gouders
Commit c1cf79ca5ced46 ("drm/amdgpu: use IP discovery table for renoir") introduced a NULL pointer dereference when booting with amdgpu.discovery=0, because it removed the call of vega10_reg_base_init() for that case. Fix this by calling that funcion if amdgpu_discovery == 0 in addition to the case that amdgpu_discovery_reg_base_init() failed.

2020-10-07gpio: pca953x: Survive spurious interruptsMarc Zyngier
The pca953x driver never checks the result of irq_find_mapping(), which returns 0 when no mapping is found. When a spurious interrupt is delivered (which can happen under obscure circumstances), the kernel explodes as it still tries to handle the error code as a real interrupt. Handle this particular case and warn on spurious interrupts.
