net: ipa: more include file cleanup All of the config data files and all of the register definition files (plus a few others) use GSI_EE_AP, which is defined in "ipa_version.h". Include that header where it's needed. All of the IPA register definition files include "../ipa.h", though none of them need anything defined there. Similarly, all of the GSI register definition files include "../gsi.h", but don't need anything defined there. Remove these unnneded includes. All of the configuration data files include "../gsi.h", though none of them need anything defined there, so remove these includes. Remove other includes of local header files that are not required.

net: ipa: include some standard header files Some IPA header files use types defined in <linux/types.h>, but do not include that file: - In "ipa_mem.h", the ipa_mem structure has u16 and u32 fields - In "ipa_power.h", ipa_power_retention() takes a bool argument, and ipa_core_clock_rate() returns u32 - In "ipa_version.h", ipa_version_supported() returns bool Include it in these files to satisfy their dependencies. The ipa_qmi structure (defined in "ipa_qmi.h") contains a work structure, so include <linux/workqueue.h> in there. All of the data and register definition files, as well as "reg.h", use the ARRAY_SIZE() macro. Include <linux/array_size.h> everywhere it's used. Similarly, all register definition files (and a few others) use the GENMASK() macro, so include <linux/bits.h> to ensure it's defined where used. BIT() becomes available by including this file also.

net: ipa: fix a surprising number of bad offsets A recent commit eliminated a hack that adjusted the offset used for many GSI registers. It became possible because we now specify all GSI register offsets explicitly for every version of IPA. Unfortunately, a large number of register offsets were *not* updated as they should have been in that commit. For IPA v4.5+, the offset for every GSI register *except* the two inter-EE interrupt masking registers were supposed to have been reduced by 0xd000.

net: ipa: kill ev_ch_e_cntxt_1_length_encode() Now that we explicitly define each register field width there is no need to have a special encoding function for the event ring length. Add a field for this to the EV_CH_E_CNTXT_1 GSI register, and use it in place of ev_ch_e_cntxt_1_length_encode() (which can be removed).

net: ipa: kill gsi->virt_raw Starting at IPA v4.5, almost all GSI registers had their offsets changed by a fixed amount (shifted downward by 0xd000). Rather than defining offsets for all those registers dependent on version, an adjustment was applied for most register accesses. This was implemented in commit cdeee49f3ef7f ("net: ipa: adjust GSI register addresses"). It was later modified to be a bit more obvious about the adjusment, in commit 571b1e7e58ad3 ("net: ipa: use a separate pointer for adjusted GSI memory"). We now are able to define every GSI register with its own offset, so there's no need to implement this special adjustment. So get rid of the "virt_raw" pointer, and just maintain "virt" as the (non-adjusted) base address of I/O mapped GSI register memory. Redefine the offsets of all GSI registers (other than the INTER_EE ones, which were not subject to the adjustment) for IPA v4.5+, subtracting 0xd000 from their defined offsets instead. Move the ERROR_LOG and ERROR_LOG_CLR definitions further down in the register definition files so all registers are defined in order of their offset.

net: ipa: define more fields for GSI registers Beyond the CH_C_QOS register, two other registers whose offset is related to channel number have fields within them. Define the fields within the CH_C_CNTXT_0 GSI register, using an enumerated type to identify the register's fields, and define an array of field masks to use for that register's reg structure. For the CH_C_CNTXT_1 GSI register, ch_c_cntxt_1_length_encode() previously hid the difference in bit width in the channel ring length field. Instead, define a new field CH_R_LENGTH and encode the ring size with reg_encode(). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

net: ipa: define GSI CH_C_QOS register fields Define the fields within the CH_C_QOS GSI register using an array of field masks in that register's reg structure. Use the reg functions for encoding values in those fields. One field in the register is present for IPA v4.0-4.2 only, two others are present starting at IPA v4.5, and one more is there starting at IPA v4.9. Drop the "GSI_" prefix in symbols defined in the gsi_prefetch_mode enumerated type, and define their values using decimal rather than hexidecimal values.
