The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Previously, there were only strict_strtol(), strict_strtoul(), strict_strtoull(), and strict_strtoll(). Thus, when converting to the variables, only long, unsigned long, unsigned long long, and long long can be used. However, kstrto*() provides various functions handling all types of variables. Therefore, the types of variables can be changed properly. Signed-off-by:

Some of the defaults were missing or unclear. In particular, I suspect the defaults were documented assuming there were still module parameters and taking the default module parameters into account. Now, the defaults are the values that will get chosen when the params passed to dwc2_hcd_init are all -1. Signed-off-by:

The HWCFG4 register stores the supported utmi width values (8, 16 or both). This commit reads that value and validates the configured value against that. If no (valid) value is given, the parameter defaulted to 8 bits previously. However, the documentation for dwc2_core_params_struct suggests that the default should have been 16. Also, the pci bindings explicitely set the value to 16, so this commit changes the default to 16 bits (if supported, 8 bits otherwise). With the default changed, the value set in pci.c is changed to -1 to make it autodetected as well. Signed-off-by:

Before, the hwcfg registers were read at device init time, but interpreted at various parts in the code. This commit unpacks the hwcfg register values into a struct with properly labeled variables at init time, which makes all the other code using these values more consise and easier to read. Some values that were previously stored in the hsotg struct are now moved into this new struct as well. In addition to the hwcfg registers, the contents of some fifo size registers are also unpacked. The hwcfg registers are read-only, so they can be safely stored. The fifo size registers are read-write registers, but their power-on values are significant: they give the maximum depth of the fifo they describe. This commit mostly moves code, but also attempts to simplify some expressions from (val >> shift) & (mask >> shift) to (val & mask) >> shift. Finally, all of the parameters read from the hardware are debug printed after unpacking them, so a bunch of debug prints can be removed from other places. Signed-off-by:

Bits 16-31 are reserved, so the old code just reads the whole register to get bits 0-15, assuming the reserved bits would be 0 (which seems true on current hardware, but who knows...). This commit properly masks out the reserved bits when reading and doesn't touch the reserved bits while writing. Signed-off-by:

For calculating FIFO offsets, the sizes of preceding fifos need to be known. For filling the GDFIFOCFG register, these fifo sizes were read from hardware registers. However, these values were written to these registers just a few lines before, so we can just use the values written instead. Signed-off-by:

For some reason, the value of the HPTXFSIZ register was built in the ptxfsiz variable, while there was also a hptxfsiz variable availble. Better just use that and remove the (now unused) ptxfsiz variable. Signed-off-by:

The value of the hcchar register is built from individual values by shifting and masking. Before, the debug output extracted the individual values out of the complete hcchar register again by doing the reverse. This commit makes the debug output use the original values instead. One debug message got removed, since it would always print a fixed value of zero. Signed-off-by:

This line extracted the available queue space without properly shifting it. Since the code only cared wether it was zero or not, it worked as expected without the shift, but adding shift makes the code cleaner. While we're here, store the result in a helper variable that was already declared to increase readability a bit more. Signed-off-by:

Various register fields wider than one bit have constants defined for their value. Previously, these registers would define the values as they appear in the register, so shifted to the right to the position the value appears in the register. This commit changes those constants to their natural values (e.g, 0, 1, 2, etc.), as they are after shifting the register value to the right. This also changes all relevant code to shift the values before comparing them with constants. This has the advantage that the values can be stored in smaller variables (now they always require a u32) and makes the handling of these values more consistent with other register fields that represent natural numbers instead of enumerations (e.g., number of host channels).

Previously, the max_packet_count could be set to 1 << x, where x is the number of bits available (width + 4 in the code). Since 1 << x requires x + 1 bits to represent, this will not work. The real maximum value is (1 << x) - 1. This value is already used the default when the set value is invalid, but the upper limit for the set value was off-by-one. This change makes the check the same as the one for max_transfer_size, which was already correct. Signed-off-by:

A generic set of FIFOSIZE_* constants is defined which applies to all fifo size and offset registers. It is already used for both the GNPTXFSIZ and HPTXFSIZ registers, but it applies to DPTXFSIZN as well. Some of these also had specific constants defined. This patch removes the specific constants and documents to use the generic constants. Note that the removed constants weren't actually used. Instead, most of the related code uses hardcoded masks and shifts. But given that subsequent patches will be moving that code around and introducing the constants in the process, this patch leaves those untouched. Also note that the GRXFSIZ register also contains a fifo size, but there is no corresponding start address register (it is always the first fifo in memory), the layout of the GRXFSIZ register is different and cannot use the same constants.
