net: ipa: don't configure IDLE_INDICATION on v3.1

2022-10-26T02:49:13+00:00

IPA v3.1 doesn't support the IDLE_INDICATION_CFG register, this was causing a harmless splat in ipa_idle_indication_cfg(), add a version check to prevent trying to fetch this register on v3.1 Fixes: 6a244b75cfab ("net: ipa: introduce ipa_reg()") Signed-off-by: Caleb Connolly Reviewed-by: Alex Elder Tested-by: Jami Kettunen Link: https://lore.kernel.org/r/20221024234850.4049778-1-caleb.connolly@linaro.org Signed-off-by: Jakub Kicinski

net: ipa: define even more IPA register fields

2022-09-28T01:42:51+00:00

Define the fields for the FLAVOR_0, IDLE_INDICATION_CFG, QTIME_TIMESTAMP_CFG, TIMERS_XO_CLK_DIV_CFG and TIMERS_PULSE_GRAN_CFG IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers. Use ipa_reg_decode() to extract field values from the FLAVOR_0 register. Remove the definition of the no-longer-used *_FMASK symbols. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: define more IPA register fields

2022-09-28T01:42:51+00:00

Define the fields for the LOCAL_PKT_PROC_CNTXT, COUNTER_CFG, and IPA_TX_CFG IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers. Remove the definition of the *_FMASK symbols as well as proc_cntxt_base_addr_encoded(), because they are no longer needed. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: define some more IPA register fields

2022-09-28T01:42:50+00:00

Define the fields for the SHARED_MEM_SIZE, QSB_MAX_WRITES, QSB_MAX_READS, FILT_ROUT_HASH_EN, and FILT_ROUT_HASH_FLUSH IPA registers for all supported IPA versions. Create enumerated types to identify fields for these registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers rather than using the *_FMASK preprocessor symbols. Remove the definition of the now unused *_FMASK symbols. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: define CLKON_CFG and ROUTE IPA register fields

2022-09-28T01:42:50+00:00

Create the ipa_reg_clkon_cfg_field_id enumerated type, which identifies the fields for the CLKON_CFG IPA register. Add "CLKON_" to a few short names to try to avoid name conflicts. Create the ipa_reg_route_field_id enumerated type, which identifies the fields for the ROUTE IPA register. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers rather than using the *_FMASK preprocessor symbols. Remove the definition of the now unused *_FMASK symbols. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: define COMP_CFG IPA register fields

2022-09-28T01:42:50+00:00

Create the ipa_reg_comp_cfg_field_id enumerated type, which identifies the fields for the COMP_CFG IPA register. Use IPA_REG_FIELDS() to specify the field mask values defined for this register, for each supported version of IPA. Use ipa_reg_bit() to build up the value to be written to this register rather than using the *_FMASK preprocessor symbols. Remove the definition of the *_FMASK symbols, along with the inline functions that were used to encode certain fields whose position and/or width within the register was dependent on IPA version. Take this opportunity to represent all one-bit fields using BIT(x) rather than GENMASK(x, x). Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: introduce ipa_reg()

2022-09-28T01:42:50+00:00

Create a new function that returns a register descriptor given its ID. Change ipa_reg_offset() and ipa_reg_n_offset() so they take a register descriptor argument rather than an IPA pointer and register ID. Have them accept null pointers (and return an invalid 0 offset), to avoid the need for excessive error checking. (A warning is issued whenever ipa_reg() returns 0). Call ipa_reg() or ipa_reg_n() to look up information about the register before calls to ipa_reg_offset() and ipa_reg_n_offset(). Delay looking up offsets until they're needed to read or write registers. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: use IPA register IDs to determine offsets

2022-09-28T01:42:49+00:00

Expose two inline functions that return the offset for a register whose ID is provided; one of them takes an additional argument that's used for registers that are parameterized. These both use a common helper function __ipa_reg_offset(), which just uses the offset symbols already defined. Replace all references to the offset macros defined for IPA registers with calls to ipa_reg_offset() or ipa_reg_n_offset(). Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: encapsulate updating three more registers

2022-09-24T03:56:28+00:00

Create a new function that encapsulates setting the BCR, TX_CFG, and CLKON_CFG register values during hardware configuration. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski
